BATTERY CONNECTION.

Specification of Letters Patent.

To all whom it mtg concern:

Be it known that I, SIDNEY J HALL, a citizen of the United States, residing at Depe'w, in the count of Erie and State of New York, have in ented certain new and useful'lm rovements in Battery Connecich the following is'a specification;

vThis invention relates to connecting devices for electric batteries.

The object of the invention is to provide a; connecting device for uniting one cell of battery to another by solderingthe junctions, of such, a character that well soldered connections may be made without resort to very' high temperatures or longmaintainecl temperatures that might ten distort the soft metal battery terminals This object is aocomglished by providing a closes the bottom to melt or short section ofmeta such as a brass castthe section .is a receptacle, open top. and bottom, within which a suit,- a 1y formed battery terminal may be closely fitted; 'the battery terminal substantially side of-the receptacle and leaves a cup shaped chamberwith an open to Ho receive and Ti ing at one end of hold the molten solder. e other end of the'connecting device is provided with a socket toreceive the end of a section of cablc,'or other suitable conductor, to which it is soldered at the junction.

These two soldered junctions are made in succession and to the end that the heat applied to solder one junction may not be co1nmunicated to the other soldered junction and m lt the solder there is provided a nee-l;

or ortion of reduced cross section interthis neck first described chamber ranged vertically with 4 shovvn in a horizontal position.

The is prefierably ar the opening at the top; the second described junction may be either vertical or horizontal, it is herein The accompanying drawing illustratesthe invention the connecting device unit- Figure 1 shows cells; Fig, 2 is a vertical ing two adj scent cross section; Fig. 3 is an elevation oi a cell terminal; Fig. t is a view r h I ofthe same at 'angles to Fig. 3; Fig. 5 is a top plan view of the connector and Fig. dis a vertical, central cross section.

of a flexible conductor The. connecting device a in its preferred form is a short casting of brass; the cells of batteryha ve fixed. terminals 8, cylindrical at the top 9, and may be perforated as shown at 10, the perforation being useful for connecting to any one of a series of cells, or in grouping cells, the projection 11 at the bottom of the part '8 and also the projection 15! at right angles thereto furnish convenicnt means for unitin the terminal with the, lug or strip 13 uniting the several plates of like name of a cell together. In. Fig. 1 I have only shown one terminal post 8 for each cell and one connector 0 for each cell with cable 11 connecting them. I have not shownrthe second terminal post and the conneetions therefrom toward other cells as it is understood that these may be .of the same construction as those shown.

The connecting device a has a receptacle 14; at one teri'ninel; this is preferably circu-' lar to fit the round terminal post 9 of the battery cell, the terminal and receptacle should fit as shownjn Fig. '2. The terminal 9 should enter the receptacle l4 far enough to leave an open top chamber in the recep- .tacle 14 to catch and hold molten'sol'der in-- troduced to solder the junction of the parts Patented J uiie 13, 1911; Application Bled February 2B, 1938.

9 and i l; the solder is shown at 20. The

opposite end of the section or connecting device is in the form of a cylinder 15, counterbored as shown at 16 to receive the end 17 d and its acid proof insulating material 18. Molten solder 20 is introduced between the surfaces of the parts 15 and 17.- These two junctions are made successively and it is desirable to. guard against melting the solder at one junction while tion. rice 0 has an intermediate section of r ced. mass, like'a neck 'n; .this retards heat con-- duction and is of sufficient extent topermit of necessary electrical conduction.

In the practical use of the connecting device the cells areassemblcd and set .u and the connectors provided in in .Fig. i g a pair of connectors c is united'by a section of insulated flexible conductor or r cable (1, the rings 14 are placed over'the pairs, as s own terminals 9, and the junction is filled with neck i prevents 'fus'cd metal or solder. The presence of the heat conduction during the soldering operation which might otherwise result in freeing the fleizible conduetorhd from its junction with the terminal 15. The substantial union between the connector and the terminal post 9 is made at the end of the post where in melting the solder the heat can be directly applied so that neither a high temperature nor a long maintained heat is necessary to make a good union at this oint. The terminal st 9, therefore, 1s not substantially heated, nor is there agreat amount of heat that will be conducted through the connector to the soldered connection in the orifice at the other end of the connector. Moreover, because of the same feature of construction the connector can be readily unsoldered and separated from the post with out such an amount of heat being applied as to be detrimental in these respects.

What I claim and desire to secure by Letters Patent is:

'1..A battery, connector composed of a short section of metal, and a socket at one end to receive a soldered connection to a.

cell said connector having an intermediate neck in mass sufficiently reduced to retard conduction oi heat from one end to the other.

2. A battery connection, comprising a connector composed of a short section of metal and a terminal soldered to one end thereof for electrically connecting the connector to a. battery cell, said connector having a section or neck of reduced mass intermediate the terminals of said section, said mass being sufiiciently reduced to retard heat conduction and suppl electricconduction to the extent required.

3. A." connector for battery cells consisting of a piece of metal arranged and constructed at two points to receive soldered electricaloonnections and having a neck in termediate said points sufiiclently reduced .to materially retard the conduction of heat .from one point to the other.

4. 'A connection for battery cells, comprising a strip of metal, a battery terminal soldered to one end of said stri and a conducting member solde d to t e other end of said strip, said st vi 1 at one end being inthe form of areceptacle to surround and extend above the battery terminal and said strip having an intermediate zone sufliciently reduced to retard the conduction of heat from one end to the other.

' 5. A connector for battery cells consisting of an integral piece of metal arranged and constructed at two points to recelve electrical connections of the fusible type and having an integral neck intermediate i;sa1d points sufficiently reduced in cross secheat from one oint to the other.

6. The coinblnation with a circular terminal post of a storage battery of a connector having a circular opening at one end embracing said post, the walls of said opening extending u wardly and diver-gently beyond the end 0 said post, a soldered connection between the walls of said 0 ening and the ends of said post and a flexib e conductor connected to the other end of said connector said connector having a. neck A.
